An active self-cleaning device for transparent substrates includes a transparent substrate, a piezoelectric transducer array formed on essentially entire transparent substrate surface, including a central area of the transparent device, and an electronic system configured to actuate the piezoelectric transducer array to clean a surface of the substrate. Such a device may be used for applications such as LIDAR, radar and camera enclosures, solar cell panel cover glasses, vehicle windshields, windows, sunroofs and headlamps, street lighting and information displays.
